PV of Cash Streams

[Fitin1rb]

Hello - 

I am looking for a way to calculate the PV of rental streams in Power BI.  This is a simple calculation in Excel (using the PV formula), but I have not found an easy way to complete this in Power BI.  Has anyone done PV calculation in Power BI or found a work around for calculating PV of streams?

Thanks
Ryan

Hello everyone,

I have resolved this at work only moments ago, so I thought I'd share as I couldn't find the answer on here!

So firstly we use the formula that MS provides for what PV is:

Then we derive what a value for PV would look like:

So if we create a new table with rate, nper, pmt and a known-good value to compare to, we can work out this formula (knowing that type =0 for payments at end of term and that fv=0 if we are not specifying a future value outright):

PVColumn = (

               -

                  ( [pmt]*( 1+ ( ([Rate]/12.0)*0) ) )

                  *

                  ( ( (POWER( (1 + ([Rate]/12.0) ), [nper]) ) -1)

                    /

                    ( [Rate]/12.0)

                  )

            )

            /

            (POWER( (1 + ([Rate]/12.0) ), [nper]) )

I have stored and linked the .pbix Proof of Concept file for you to look at on my personal site,

Hi @Fitin1rb,

Have you tried using the XNPV function(DAX) to create a measure to calculate the present value? Here is also an article about Difference Between NPV and XNPV for your reference.

Hey @v-ljerr-msft XNPV does not work for what I need to do.  I do not have streams table, but rather, it is a transaction/asset table that has a static rental over a specified number of periods which is why I would need PV.  Very surprised that Power BI does not have the PV function available.  Below is a single line item of my data.  Total Revenue Net COF and 'NII' are calculated with PV which I am trying to get to in Power BI but I cannot seem to get there.

Thanks !
